HTML reports should set white as default background color

my desktop (and therefore the browsers) use a dark theme, ie light text on a dark background. Some browsers (but not all) set white as the default background color and black as default (text) color for HTML pages.

Firefox however does not (at least on Linux) and the HTML coverage reports become unreadable (see attached screenshot):

The problem can be fixed by adding the following CSS snippet to the 'body' (possible 'body, html') declarations in base.css

background-color: white;

Thanks for considering Christian.
